YALLA SHOOT Piezo and capacitance switches are the two most popular non-mechanical switch types currently available. A very commonly seen tamper-resistant switch is the ignition switch in most motor vehicles. A variant of this design is to use a computerized keypad and a secret code that activates and deactivates the switches. Vandal-resistant switches are usually protected by the use of robust materials, such as thick stainless steel or heavy-duty plastics. A few types are capable of switching 120 or 220 V AC power at several amperes, and are better suited to direct switching of the AC power to a device than the gold-plated contact switches.|Dibelakang Terdapat Slot Tambahan Untuk Modul
